Patent DE-8904802-U1 (DE)
IPC: G02C5/22
Filed: 1989-04-17
Abstract: The invention relates to a spectacle frame with a screw connection secured against unscrewing for mounting parts, in particular hinged parts. Provided for this purpose is a one-piece metal screw connection which does not lead to self-seizure nor to jamming of the opposing jointed rings nor, furthermore, require any plastic insert, i.e. can remain installed during soldering work. This is achieved when, given a conical angle of between 20 DEG  and 40 DEG , in particular 30 DEG , with an adjoining clearance angle, there is provided in a mounting part when the screw head is screwed in a differential angle of 1 DEG  to 3 DEG  between the screw head and receptacle in conjunction with a slim conical bore. As a result, in the event of strong tightening of the screw, on the one hand, self-loosening due to high friction is avoided and, on the other hand, too high a contact stress of the hinge rings is also avoided.
